Each polio consists of 4 doses and rack measles vaccination consists of 2 doses.Last year potter gave out a total of 60 vaccinations and that consisted of a total 128 doses.How many polio vaccinations and how many measles vaccinations did dr potter give last year?
Answer:
4 polio
56 measles
Step-by-step explanation:
Write equations to represent the problem
let x be the number of vaccinations for polio
let y be the number of vaccinations for measles
x + y = 60 Equation for vaccinations
4x + 2y = 128 Equation for doses
Solve the system using substitution. Rearrange x + y = 60 to isolate one variable.
x = 60 - y
Substitute x for 60-y in the other equation
4x + 2y = 128
4(60-y) + 2y = 128 Distribute over brackets
240 - 4y + 2y = 128 Collect like terms. They have the variable "y"
240 - 2y = 128 Subtract 240 from both sides
-2y = 128 - 240
-2y = -112 Divide both sides by -2
y = -112/-2
y = 56 Number of measles vaccinations
Substitute y for 56 in x + y = 60
x + y = 60
x + 56 = 60
x = 60 - 56
x = 4 Number of polio vaccinations
Therefore Dr. Potter gave out 4 polio vaccinations and 56 measles vaccinations.

Which property is illustrated by the statement?
(2+3.4) + 6 = 2 + (3.4+6)
Associative Property of Addition
Commutative Property of Multiplication
Inverse Property of Multiplication
Commutative Property of Addition
Answer:
The given expression represents the Associative Property of Addition.
Step-by-step explanation:
Here, the given expression is given as:
(2+3.4) + 6 = 2 + (3.4+6)
Now, for any 3 terms a, b and c the given properties in the options are described as:
1. Associative Property of Addition
(a +b) + c = a + (b + c)
2. Commutative Property of Multiplication
a x b = b x a
3. Inverse Property of Multiplication
[tex]a \times \frac{1}{a} = 1[/tex]
4. Commutative Property of Addition
a+ b = b + a
Hence, from the given expression,we can see that:
(2+3.4) + 6 = 2 + (3.4+6)
⇒(a +b) + c = a + (b + c)
Hence, the expression represents the Associative Property of Addition
Final answer:
The statement (2+3.4) + 6 = 2 + (3.4+6) demonstrates the Associative Property of Addition, indicating that the sum of a set of numbers is the same regardless of how the numbers are grouped.
Explanation:
The property illustrated by the statement (2+3.4) + 6 = 2 + (3.4+6) is the Associative Property of Addition. This property states that when adding three or more numbers, the way in which the numbers are grouped does not change the sum. For instance, as shown in the statement, (a + b) + c equals a + (b + c), which means that the groupings of the numbers can be changed without affecting the total sum. This is not to be confused with the Commutative Property of Addition, which is about the order of the numbers and states that A + B equals B + A. The commutative property tells us that we get the same result whether we add 2 + 3 or 3 + 2. However, the question explicitly deals with the grouping of numbers, not the order, thus confirming that the associative property is in use.

{(2, 3), (8,9)
Answer:
{(-2,3), (7,-6) } -----> y - 15 = -[tex]x^{2}[/tex] + 4x
x + y = 1
{(-5, 8). (3,0) } ----> y + 12 = [tex]x^{2}[/tex] + x
x + y = 3
{(-2,5),(3,-5) } -----> y + 5 = [tex]x^{2}[/tex] - 3x
2x + y = 1
{(2, 3), (8,9)} -----> y-17 = [tex]x^{2}[/tex] - 9x
-x + y = 1
Step-by-step explanation:
The simplest way to find the answer is by solving all the equations and finding the value of x and y for each of them.
Solving the equations ->
y + 12 = [tex]x^{2}[/tex] + x
x + y = 3
Substitute y = 3-x from second equation to first and solving the quadratic equation obtained i.e solving [tex]x^{2}[/tex] + 2x -15 = 0 , we get values of x = -5 , 3 and the corresponding values of y by substituting values of x in second equation , y = 8, 0 respectively. So, solution matched = {(-5, 8). (3,0) }.
Similarly solving other equations using exactly the same method as above we get the following solutions,
For,
y - 15 = [tex]x^{2}[/tex] + 4x
x - y = 1
we don't get any integer solution for this hence it has no match.
For,
y + 5 = [tex]x^{2}[/tex] - 3x
2x + y = 1
we get x = 3,-2 and corresponding y = -5,5
So, solution is {(-2,5),(3,-5) }
For,
y- 6 = [tex]x^{2}[/tex] – 3x
x + 2y = 2
we again don't get any integer solution for x and y so this has no match.
For,
y-17 = [tex]x^{2}[/tex] - 9x
-x + y = 1
we get x = 2,8 and corresponding y = 3,9
So, {(2, 3), (8,9)} is the solution match.
Lastly for,
y - 15 = -[tex]x^{2}[/tex] + 4x
x + y = 1
we get x = -2,7 and corresponding y = 3,6
So, {(-2,3), (7,-6)} is the solution match.

During the summer, Joshua plans to work on his uncle’s soybean farm. His uncle says that Joshua has two options for being paid. For the first option, Joshua earns $20 each day he works. For the second option, he earns one nickel for agreeing to work, and that amount doubles each day he works after that. Joshua plans on working 3 days a week for 8 weeks. Which option should he choose?
Answer:
The second option is best to choose.
Step-by-step explanation:
Joshua plans on working 3 days a week for 8 weeks. Therefore, Joshua will work for (8 × 3) = 24 days.
For the first option, Joshua earns $20 each day he works. So, in 24 days he will earn (20 × 24) = $480.
For the second option, he earns one nickel for agreeing to work, and that amount doubles each day he works after that.
So, the total earning of Joshua after 24 days of work will be
0.05 + 0.1 + 0.2 + 0.4 + 0.8 + 1.6 + ......... up to 24 terms {Since 1 nickel is equal to $0.05}
Now, this is an G.P. series sum and first term is 0.05, common ration is 2 and the number of terms is 24.
So, the sum = [tex]0.05 \times \frac{2^{24} - 1 }{2 - 1}[/tex]
= $838860.75
Therefore, the second option is best to choose. (Answer)
Final answer:
To decide between the payment options, Joshua should calculate the total income for the first option ($480) and compare it to the exponentially growing total of the second option, which would be far greater due to the daily amount doubling. Therefore, the second option is the more lucrative choice.
Explanation:
The student's question pertains to determining which of the two payment options offered by Joshua's uncle for work on a soybean farm is more advantageous. Joshua needs to calculate the total earnings for each option over the course of 8 weeks, given that he will work 3 days each week. For option one, it is straightforward: $20 per day times 3 days per week times 8 weeks equals a total of $480. Option two, however, requires calculating the total amount for a doubling sequence starting with a nickel ($0.05).
For option two, the earnings for each week will look like this:
Week 1: Day 1 = $0.05, Day 2 = $0.10, Day 3 = $0.20
Week 2: Day 1 = $0.40, Day 2 = $0.80, Day 3 = $1.60
...and so on. The amount doubles each day Joshua works.
Calculating this for the 24 days (3 days times 8 weeks) will show that on day 24, Joshua's daily earnings would be $0.05 ×223 (since the first day is $0.05 and does not double).
Comparing the total earnings from both options will reveal that Joshua will earn significantly more with the second option. Therefore, Joshua should choose the second payment option.
How do the numbers compare
The fact family model represents the relationship between
the numbers 8, 7, and 15.
15 is 7 more than 8.
15 is 8 less than 7.
7 is 15 less than 8.
07 is 8 more than 15.
Answer:
A
Step-by-step explanation:
8+7=15
For the numbers 8, 7, and 15, the true statements are '15 is 7 more than 8' and, when rephrased correctly, '7 is 8 more than 15'. The concept of significant figures plays an important role in mathematical operations to maintain the accuracy of results based on the precision of original numbers.
Explanation:The fact family model is used to represent the relationship between three numbers that can form addition and subtraction statements. For the numbers 8, 7, and 15, only some of the given statements are true. Let's verify each statement:
15 is 7 more than 8: This statement is true, as 8 + 7 equals 15.
15 is 8 less than 7: This statement is false, as adding 8 to 7 gives us 15, not taking 8 from 7.
7 is 15 less than 8: This statement is false, as subtracting 15 from 8 would give us a negative number, not 7.
7 is 8 more than 15: This statement is true when we rephrase it correctly as 7 + 8 equals 15.
Therefore, only two statements are accurate: '15 is 7 more than 8' and '7 is 8 more than 15' when considered as 7 + 8 = 15.
The subject of significant figures and rounding is also related to mathematics. When performing mathematical operations, significant figures are crucial to ensure that our answers are as accurate as the precision of the numbers we started with, without overstating the certainty of our results. This becomes important when adding, subtracting, multiplying, or dividing numbers in mathematics.

YC = 25 units, CX = 5 units, YD = 20 units.
We know that,
If CD is parallel to XZ , then the line CD divides the sides XY and YZ of the triangle XYZ proportionally. This is true by triangle proportionality theorem.
Therefore, the lengths YC, CX, YD and DZ are in proportion. This gives,
[tex]\frac{YC}{CX}=\frac{YD}{DZ}[/tex]
Rewrite in terms of DZ. This gives,
[tex]DZ=\frac{YD\times CX}{YC}[/tex]
Plug in [tex]YC=25,CX=5,YD=20[/tex]. Solve for DZ.
[tex]DZ=\frac{20\times 5}{25}\\\\DZ=\frac{100}{25}=4[/tex]
Therefore, the length of DZ is 4 units.
